Hi,

i managed to get the tv out running on my matrox g450.
The main problem now is that the picture is black and white and
unstable.
Are there any things i can do to fine tune the output?
Also the configuration of X was a bit incomplete,
he mist to write the config for the first monitor.

I use a debian/sid, nova-t(90002) and a PAL TV.


here is my xf86config.
